Not sure if I was just imagining it, but Park City had some groomed blacks when I went last month. The black right off of Bonanza lift was groomed, meaning it had moguls the day before and were gone the next. The blacks on the front bowl leading to the base (silver king, etc) were groomed, too. I built up scary speed on the steepest portions, but just had to keep going. I learned that going on too much on one edge to slow down/stop will usually start a very long side skid down the run. Sounds like you had a blast on your trip.
